The best way to report bugs (or otherwise send a quick communication) is to use the "Contact Five12" option built into Numerology 3. When running Numerology in app or ReWire modes, there is a "Contact Five12" item in the "Numerology" menu (i.e. the main app menu). In AU and VST land, click the little "Mail" button next to the Five12 logo. You'll get an easy-to-use form, and in app/ReWire modes, it will automatically include any relevant log files.
